Do not install openstack-quantum-openvswitch-agent in server recipe

This is as SUSE-only fix (Ubuntu code path isn't affected). The
openstack-quantum-openvswitch-agent package is already installed as part
of the common_install recipe.

As a side-effect, this fixes the CHEF-3694 caused by this package being
installed twice:

WARN: Cloning resource attributes for package[openstack-quantum-openvswitch-agent] from prior resource (CHEF-3694)
WARN: Previous package[openstack-quantum-openvswitch-agent]: /var/chef/cache/cookbooks/quantum/recipes/server.rb:24:in `from_file'

Set dnsmasq_dns_server option in dhcp_agent.ini

This option is needed to allow dnsmasq process (which is started for
every quantum subnet) to forward dns queries.

Enable access to 169.254.169.254 directly over the physcial interface

Some Linux system images assume that 169.254.0.0/16 is reachable directly
over the physcial interface (this is the default behavior in nova-network).
This patch bring backs this behavior to quantum based network.
